re Cyclone efficiency.
Dear Babli
As mentioned by Raj for preheater top stage cyclones.
You know the feed from your scales and the return dust can be measured in direct operation by truck scale.
So you need an discharge point and later you can put the truck with the matierial to the bridge scale and you will have a quite good indication.
Cheers

re Cyclone efficiency.
Hi Babali,
Procedure of drop test for measuring dust collection effiiency of top stage cyclone of pre-heater tower:
1.During steady state condition of kiln and raw mill stop condition you may divert the collcted dust in the ESP or Bag House in downstream cicuit after kiln ID Fan and Preheter Fan.
2.The collected hot and fine dust in any close container/tractor.Please ensure safety of your team prior to initiate the test.
3.Collected dust should be weighed and collection time should also be record.
4.Note down the total kiln feed TPH fed to the kiln.
5.Divide the dust collected TPH by Kiln Feed Tph and calculate the dust collection efficiency % of the top stage cyclone.
Alternatively a less accurate way is to measure the dust concentration at the downcomer duct of preheater tower and convert it to TPH.
I do hope that I have clarified your query.
